Anyone interested in getting a binaural beat program could try www.bwgen.com, the free version is limited and the full version is expensive but i use it fairly often to try and initiate lucid dreams or study (Study Aid has helped from time to time).

For those who dont know what it is.

Basically its not so much music so much as a series of beats, what happens is with headphones (need to use headphones) one pitch is played in one ear and one in the other the brain then hears the difference, this is useful as this allows us to hear beats that we normally cant hear (its not so much hearing so much as the cereberal cortex interpreting it), we can then use these to induce differing states of mind (Alpha, Beta, Gamma, Delta, Theta) for example if you wanted to hear say 4htz you would play 500htz in one ear and 496htz in the other.

For me i like the Theta state, best one for Lucid Dreaming, and they have found that for some people, 30 mintues of the Theta state is equivalent to 4 hours of regular sleep.

I've used binaural beats for quite a long time(almost one year in fact), and I can attest to their effects. I've tried some binaural beats which stimulate the chakras, and I could feel the location where my chakras are, vibrating and sort of "warm" up. So I know for sure that binaural beats ARE effective in entraining our minds.

I don't know, it didn't do much for me. Maybe I listened to it wrong or something lol.

It is definitely a way to entrain your brain to enter lower states of consciousness without the years of meditation practice usually required.  I would suggest a meditation machine such as the Audiostrobe which uses light and sound to help you to reach the Theta state of consciousness.  You can also download free software for your computer which uses the binaural beats.  Basicly how it works is it presents two differing frequencies to each of your ears, when they combine in your brain they form a single fequency which moves your brain to match it.  Audistrobe's website is http://www.audiostrobe.com/

I recently tried Centerpointe for a week or so.  An hour a day but stopped it because I felt it was making me anxious.  Whether it was just a coincidence I don't know.  It is definitely the nicest binaural music to listen to.  

I was listening to it on mp3.  It mentions on their website that when converted to MP3 the music loses some of its benefit.  Not sure whether it does or not ?

I've also tried Mind Tek's X-mind series briefly which is mean't to be slightly more intense than other experiences....
